Answer:

Step-by-step explanation:

A rectangle had a length of 2x-7 and a width of 3x+8y

Perimeter P = 2(l + w)

P = 2(2x - 7 + 3x + 8y)

P = 2(5x + 8y - 7)

P= 10x + 16y - 14

A bicycle wheel with radius 30cm made 1000 revolutions. What distance did it cover?​
Inga [223]

The distance covered by bicycle is 1.885 km.

What is distnace?

Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively. Distance can refer to a physical length in physics or to an estimate based on other factors in ordinary language.

Given:  A bicycle wheel with radius 30cm made 1000 revolutions.

We have to find the total distance covered by bicycle.

First to find the circumference of the bicycle wheel.

Circumference = 2πr

where, r is the radius.

Here r = 30.

So,

Circumference = 2 x π x 30 = 60π

Now to find the total distance,

D = circumference x number of revolutions.

D = 60π x 1000

D = 188,495.5592 cm

D = 188,495.5592 /1000 km

D = 1.88 km

Therefore, the distance covered by bicycle is, 1.885 km.
